Slingo is the addictive and fun combination of SLOTS and BINGO! With Slingo Supreme, we really wanted to pull out all the stops and make the ultimate Slingo game that would be a flagship product for all the Slingo fans. Slingo Supreme is the game that we've always wanted to play on our iPhones, it is the most polished, full-featured Slingo game ever. The heart of this fun new Slingo game is the innovative Supreme mode. In Supreme, as you play, you will unlock powerups.
